Title: Improvements in or relating to degreasing apparatus
IPC: C23G5/04
Filed: 1936-05-25
Abstract: In a de-greasing-apparatus for metal or other nonabsorbent articles and consisting of an open-top chamber containing solvent vapour and provided with cooling coils 8, a separate drying chamber 2 is provided adapted to receive the articles and provided with suction means to withdraw vapour from the lower part of the chamber and create a down draught therein.  The drying chamber may form a vertical or a horizontal extension of the degreasing chamber.  In the Figure, the drying chamber 2 is provided with a false bottom 16 connected to an inner chamber 3 through a spring-operated valve 9.  A duct <PICT:0475814/III/1> 7, mounted above three sides of the degreasing chamber, and the chamber 3 communicates with a suction fan 17.  The duct 7 is provided with port openings 1, and decreases in area of cross-section whereby equal suction is produced at all the ports. A movable baffle may be placed in the duct 7 as a further control upon distribution of the suction effect.  In operation, the articles are cleaned by liquid and vapour solvent, and are then placed in the drying chamber.  The weight of the articles depresses the floor 16 whereby valve 9 is opened.  The apparatus avoids losses of solvent by (1) diffusion of vapour above the vapour line, and (2) entrainment of solvent with the articles.  In a further form of drying chamber which forms a vertical extension of the degreasing chamber, a sliding lid is provided with walls on three sides, and with a suction port at the lower edge, whereby vapour is drawn downwardly from the articles.  The floor may have perforations which increase in size with the distance from the suction port.  British Specifications 362,619, 391,454, 400,997, 446,503, and Canadian Specification 343,746 are referred to.

Title: Improvements in and relating to windings of alternating current dynamo electric machines
IPC: H02K3/14
Filed: 1921-05-27
Abstract: 185,195. British Thomson - Houston Co., Ltd., and Taylor, H. W. May 27, 1921. Coils and conductors; equalizing currents in parallel-connected windings of alternating-current machines, auxiliary means for.-In alternating current generator windings in which the conductors are sub-divided into a number of paralleled sections or laminae for the elimination of eddy currents, reactances external to the machine slots are connected to the various laminations before these are connected together to a common terminal, the reactance values being such as to compensate the decreasing values of the reactance of the individual laminae in accordance with their distance from the bottom of the slot. The currents through all of the laminations accordingly experience a common total reactance before reaching the machine terminals and are, therefore, equally divided among the sections of the composite conductors. Fig. 3 shows the use of separate reactances, adapted for a composite conductor having four laminae 1, 2, 3, 4. The values are such as to bring the total reactance of the laminae 2, 3, 4 between the machine terminals up to the value of that of the lowest laminae 1 of the slot. In the form shown in Fig. 6, the reactances are in the form of a single tapped coil the sections of which have a common core. When known winding arrangements are used for partially balancing the reactances of the laminae during their passage through the winding, laminations having a common reactance may be joined together into a group which is then joined to an external reactance as above described. Fig. 8 shows this method applied to a conductor having twelve laminations which are carried through the windings and by transposition fall into groups of four between which there is no difference of reactance although there is a difference between the sections of each group. In this case, corresponding sections 1, 5, 9 or 2, 6, 10 and so on are connected together and joined by group connections to an external tapped reactance. In a threephase machine, an external reactance is used for each phase and may be connected in the neutral lead before the common earth point.

Title: Coin operated automatic coffee vending machine
IPC: A47J31/40
Filed: 1964-04-10
Abstract: 1,013,110. Coin-freed coffee vending apparatus. C. E. VALENTE, April 10, 1964 [April 12, 1963], No. 14865/64. Heading G4V. [Also in Division A4] A coin-freed hot coffee vending machine comprises an intermittently-rotatable carrier 18, 28, Fig. 7, for strainers 36 which is adapted to receive in succession a predetermined amount of ground coffee and is arranged to be moved so as to present successive strainers in position to receive ground coffee, position them above a coffee-receiving cup and invert them for the purpose of removing used coffee and making the strainers ready for re-use. As shown in Figs. 1 and 4 the carrier, which is provided with four rotatable strainer holders 28 on a hub portion 18, is mounted for rotation on a shelf 1 in the casing A of the machine. Upon insertion of a coin the carrier is stepped round through 90 degrees so as to move the strainer from the ground coffee receiving station I to the coffee brewing station II at the front of the machine where hot water is sprayed on to the grounds and the coffee dispensed down a spout 27<SP>1</SP> into a cup disposed in a recess 143 which is accessible to the customer. Reservoirs 78 containing drinking water and siliconized water supply pumps 76, 77 in the hydraulic circuits for making the coffee and operating the various components of the machine. Insertion of a coin initiates the cycle of operation of the valves in the hydraulic circuits and the start of the motor 75 of the pumps. A cup is dispensed from a stack 160 into the recess 143 together with sugar from a container 158 and a spatula from a distributer which is mounted on the door 8 of the casing. Drinking water is supplied to the chamber 10 of the brewing station II, Fig. 6, where it is heated by an element 14 controlled by a thermostat 15. After coffee from a container 145 disposed above station I is deposited by an electro-grinder 50 into the strainer 36 at that station, the strainer in question is moved round to station III by a ratchet mechanism which is fixed to the shelf 1 at station IV and acts on a notched collar portion 69 of the carrier hub. The strainer which was used for the previous operator of the machine is presented to station III where, as shown in Fig. 8, it is inverted by a forked member 55 which is rotated by a rack-and-pinion mechanism; coffee grounds fall into a bucket 147 and the strainer is flushed clean by jets of water from spray-pipes 60, 61. The strainer with the freshly-ground coffee which is then at the brewing station is clamped by an extension 25 of a cylinder 23 while a valve 38 is lifted by a piston 43 to allow the heated water from the chamber 10 to be sprayed on to the grounds through a nozzle 6. The valves are then re-set and the pumps stopped ready for the next customer.

Title: Production of aqueous dispersions of pitch, bitumens, resins and other material
IPC: C08L95/00
Filed: 1928-05-21
Abstract: 321,721. Dehn, F. B., (Flintkote Co.). May 21, 1928. Drawings to Specification. Emulsions, making.-In making emulsions of bitumens, liquid and solid hydrocarbons, natural and artificial resins, ester-gums, stearines, waxes and other material, fluxed or not with mineral or drying oils or fatty acids, insoluble mineral powders such as colloidal clays are employed as emulsifying agents and the hydrogen ion concentration of one of the phases, or of the emulsion during or after preparation is adjusted to an optimum value for good emulsification or for stability of the emulsion. The adjustment of the hydrogen ion concentration of the emulsifying agent may be effected by adding a reagent such as alum thereto or by employing suitably proportional mixtures of differing pH values or alternatively for a given emulsifying agent the pH of the principal ingredient may be adjusted, for example by the addition of oleic acid for an excessively alkaline emulsifying agent or of cumarone resin or an oil soluble organic base if the agent is too acid. The periodic adjustment of the pH of the system during emulsification to bring it to the optimum value is stated to result in an increase in the quantity of the principal ingredient emulsifiable by the process. The pH value of a prepared emulsion may also be adjusted to render the product more stable, for example against freezing. In a modified process which may be carried out in a continuous manner, the pa value of the emulsifying agent may be initially so chosen as to bring that of the final emulsion to the optimum value for dispersion, or, alternatively, may be maintained at the optimum value throughout the process by the addition of a buffer salt.

Title: Process for the manufacture of 1.3-dioxy-4-carboxy-6-phenylethyl-benzene
IPC: C07C51/15
Filed: 1927-06-07
Abstract: 272,232. Hoffmann- La Roche & Co., Akt.-Ges., F. June 4, 1926, [Convention date]. 1: 3 - Dioxy - 4-carboxy-6-phenylethylbenzene, which is suitable as an internal disinfectant, is prepared by the action of carbon dioxide upon 1 : 3-dioxy-6-phenylethylbenzene in the presence of alkali. In one example, an aqueous sodium bicarbonate solution of the 1 : 3-dioxy-6-phenylethylbenzene is treated with carbon dioxide at elevated temperature and pressure and the carboxylic acid is separated from the resulting solution by means of mineral acid. According to a second example, 1: 3-dioxy-6-phenylethylbenzene is dissolved in alcoholic soda which is then evaporated to dryness in vacuo. The dried residue is subjected to the action of carbon dioxide under pressure and at elevated temperature and concentrated hydrochloric acid and benzol then added. The 1: 3-dioxy-4-carboxy-6-phenylethylbenzene is extracted from the benzol solution as the sodium salt by means of aqueous sodium bicarbonate. 1 : 3-Dioxy-6-phenylethylbenzene is prepared by condensation of resorcin with benzylcyanide and reduction of the resulting product. The Specification as open to inspection under Sect. 91 (3) (a) comprises also an additional example in which the product is worked up by dissolving the mass obtained in treating with carbon dioxide, as in the second example, extracting with ether and precipitating the 1 : 3-dioxy-4-carboxy-6-phenylethylbenzene with hydrochloric acid as before. This subject-matter does not appear in the Specification as accepted.

Title: Improvements relating to apparatus for use in the manufacture of water gas and in other cyclical processes
IPC: C10J3/24
Filed: 1928-05-23
Abstract: 317,815. Humphreys & Glasgow, Ltd., and Stelfox, J. C. May 23, 1928. Producers. - In apparatus for mechanically carrying out water gas and other cyclic processes the valves of the plant are actuated at the desired rate and times by means of a corresponding number of couplings between the valves and a member continuously driven by a constant speed motor, the couplings being controlled by an automatic operator. A motor drives a shaft 1 which by connecting members causes a stirrup-shaped lever 4 to be constantly rocked during each cycle of operation. A number of levers 6, each corresponding to one of the apparatus valves is mounted on the same shaft 5 as the lever 4 to which pawls 7, 8 are secured and which tend to engage with the ends of levers 6 but are restrained by hinged cam bars 9, 10 which are lifted by an automatic operator. A catch 6<b> engages each valve lever when in its extreme position and is released by upward movement of its cam bar. The automatic operator comprises a pair of shafts 11, 12 geared together to make one revolution for each cycle and carrying cams 17, 18. The cam bars are connected to rods 13, 14 pivoted to levers 15, 16 which bear against the cams 17, 18. To enable the cam bars to be actuated by hand, each is provided with a lifting rod 19 supported by a pin 20 working in an eccentric slot in an arm 21 carried in spring-supported bearings 23 and rocked by a hand lever 22b. The bearings 23 can be depressed by a cam 24b on a shaft 24 by which the action of the automatic operator may be suspended. If the shaft 24 be given a quarter turn clockwise a double cam 24a holds the levers 15, 16 out of engagement with the cams 17, 18 and the cam 24b holds down the bearing 23 so that the cam bars 9, 10 are lowered and the pawls 7, 8 released from the valve levers 6, the valves being left in the positions they occupy when the shaft 24 is turned. If the shaft 24 is turned anti-clockwise, the levers 15, 16 are held out of engagement, but the cam 24b will clear the bearing 23 so that the spindle 22a will rise and cause the cam bars 9, 10 to allow the valves to be moved to the shut down position, in which any valve can' be opened or shut by a hand lever such as 6<y>. A hand wheel 30 may be used on failure of the motor. In Fig. 4, 27 is an overload alarm switch, 28 a current failure alarm switch, and 29 a dangerous overload switch, opening of which cut off the current.

Title: Electric battery-driven vehicle
IPC: B60K1/00
Filed: 1945-06-14
Abstract: 613,516. Transmitting mechanical power;  automatic control of current. DEWANDRE, A., and DACOS, F. June 14, 1945, No. 15147. Convention date, April 25, 1944. [Class 38 (iv)] In order that the power plant of a battery driven vehicle may operate at high efficiency, a shunt or compound motor is employed to permit of regenerative working, a mechanical gear-box is inserted in the drive between the motor and the road wheels-the ratio of successive gears being not more than the ratio of the speeds of the motor between which its efficiency is high and reasonably uniform- and the battery is such as will ensure a high utilizable capacity at a discharge rate corresponding to the maximum current taken by the motor over its speed range. The gears may be changed manually by a lever, a pedaloperated clutch being included between the motor and gear-box. An accelerator pedal may control the excitation of the motor. Gear changing may, however, be automatic, either under the control of a declinometer or, as shown, a controller 8 actuated by a solenoid 26 carrying the armature current of the motor 1. Vertical movement of the controller with increase in armature current selectively energizes gear-changing coils 18<SP>I</SP>-18<SP>VI</SP> over contacts 8<SP>I</SP>-8<SP>IV</SP>, 9<SP>I</SP>-9<SP>IV</SP>. A movable switch contact 11, co-operating with fixed contacts 24, 25, 27, is engaged by cams 10<SP>I</SP>-10<SP>III</SP> on the controller immediately before a change of gear and suitably modifies the speed of the motor by cutting out or fully inserting a resistance 4 included in the circuit of the motor field 17. Resistance 4 normally forms part of a pedal-operated rheostatic accelerator 5, 16, 4. Change of gear when the accelerator is in either of its extreme positions is prevented by limit switches 15, 15<SP>1</SP> which selectively energize coils 14, 14<SP>1</SP> to cause dogs 13, 13<SP>1</SP> to engage projections 12<SP>I</SP>-12<SP>IV</SP>and lock the controller. The motor is started by a separate controller (not shown). A polarized circuit-breaker 21 opens the motor circuit when the motor takes excessive current, but remains closed under all 'load conditions during periods of regeneration. In the case of a compound machine, the series winding may be automatically short-circuited during regeneration.
